摘要

PROBLEM TO BE SOLVED: To provide a magnetic resonance type irreversible circuit element for which an isolation fractional band-width is wider than before. SOLUTION: By controlling the value of the magnetic resonance half value width (ΔH) of a magnetic body, the isolation fractional band width is set to a desired value. Preferably, by turningΔH to be≥8,000 A/m, the practically sufficient isolation fractional band width is obtained. COPYRIGHT: (C)2004,JPO&NCIPI
